Mars orbiter enters safe mode after disturbance

NASA says its powerful Mars Reconnaissance Orbiter is in safe mode after being hit by a cosmic ray or solar particle.

NASA's Mars Reconnaissance Orbiter is in safe mode and in communications with Earth after an unexpected rebooting of its computer Wednesday evening, June 3.

The spontaneous reboot resembles a Feb. 23 event on the spacecraft. Engineers concluded the most likely cause for that event was a cosmic ray or solar particle hitting electronics and causing an erroneous voltage reading.

Jim Erickson, Mars Reconnaissance Orbiter project manager at NASA's Jet Propulsion Laboratory, Pasadena, Calif., said, "The spacecraft is sending down high-rate engineering data, power positive, batteries fully charged, sun pointed and thermally safe. The flight team is cautiously bringing the orbiter back to normal operations. We should be resuming our exploration of Mars by next week."

The reboot occurred at approximately 6:10 p.m. PDT (9:10 p.m. EDT) on June 3. This is the sixth time since the spacecraft began its primary science phase in November 2006 that it has entered safe mode, which is its programmed precaution when it senses a condition for which it does not know a more specific response.

That's what you get for using Windows software.

what and youd rather use an open source so that some guy who just got fired can upload some code strings to put it into the ground of the nearest moon or planet....

this isnt a windows thing, this was programmed into the satellites and into our ROVs as well that if they encounter problems they don't have a programmed solution for, they go into safe mode. This would happen no matter what OS was used on them.

The operating system used is VxWorks which is a real-time operating system. You would never dream of using Windows on a spacecraft. Having used VxWorks myself, it is one of the best RTOS around. See http://en.wikiped..._Orbiter

that was kind of my thought as well..you wouldnt stick XP on something flying millions of miles away.
